How to Make a Sweet Iced Red Eye
Fill a large glass with ice and add 1/4 oz each of vanilla, caramel, and hazelnut syrup. Pour in cold brewed coffee, top with a shot of espresso, fill with your choice of milk, and stir to combine.
A Sweet Iced Red Eye combines a shot of espresso with chilled brewed coffee, three flavored syrups, and milk over ice. The result is a bold yet sweet, refreshing coffee drink that gets its double-caffeine punch from both brewing methods.
What you need
- espresso machine
- large glass
- measuring device for syrups
- long stirring spoon
Method
Fill a large glass completely with ice
Measure and add 1/4 oz vanilla syrup to the glass
A measuring device or pump dispenser ensures a consistent pour
Measure and add 1/4 oz caramel syrup
Measure and add 1/4 oz hazelnut syrup
All three syrups together total 3/4 oz and create a layered, clean sweetness
Pour cold brewed coffee over the ice and syrups
Brew your coffee ahead of time and allow it to cool, or place it in the refrigerator before use
Expert tipStarting with cold coffee preserves the ice and keeps the drink from diluting too quickly
Top the drink with one shot of espresso
Add milk to fill the glass
Skim milk gives a lighter body; whole milk adds balance; half-and-half produces a noticeably richer flavor
Stir everything together until fully combined and serve immediately

Why this works
The red eye format draws on two brewing methods — drip coffee for volume and mellow depth, espresso for concentrated intensity — producing more complexity than either alone. Adding the syrups directly over ice before any liquid helps them distribute evenly once the coffee is poured on top. Pre-chilling the brewed coffee is the key technique: it prevents rapid ice melt that would otherwise water down both the flavor and the syrup balance. Milk added last softens the overall profile and integrates the layers into a cohesive drink.

Where beginners go wrong
- 1
Drink tastes watery
Use brewed coffee that has been fully cooled or refrigerated before pouring. Warm or hot coffee melts the ice rapidly and dilutes both the flavor and the syrups.
- 2
Syrups pool at the bottom
Stir thoroughly after adding all ingredients. Placing the syrups in first, before the coffee and milk, also encourages more even mixing.
- 3
Sweetness is off
The transcript's starting point is 1/4 oz of each syrup. Dial individual flavors up or down in small increments until the balance suits your preference.
- 4
Espresso character is lost
Pour the espresso shot last, right before the milk, so it floats briefly on top and its aroma is present from the first sip before stirring.
What you should taste
Sweet and refreshing with a pronounced coffee backbone. The vanilla, caramel, and hazelnut syrups deliver a clean, rounded sweetness rather than any single dominant flavor, while the espresso shot sharpens the finish against the smoother brewed coffee base.
FAQ
What exactly is a Red Eye?
A Red Eye is a combination of a shot of espresso added to brewed drip coffee. The Sweet Iced version builds on that base by adding flavored syrups and milk over ice for a cold, sweetened variation.
Does the brewed coffee have to be cold?
The transcript notes you can use it hot or cold, but the creator prefers to brew the coffee ahead and let it cool down or refrigerate it. Cold coffee protects the ice and keeps the drink from becoming overly diluted.
Which milk is best for this drink?
The transcript lists skim milk, whole milk, and half-and-half as options. The creator specifically notes that half-and-half gives the drink a rich flavor, making it the choice if you want a more indulgent result.
